TRAIN-DOORS CQNTROL.

T 0 all whom it may concern Be it known that '1, VER ON a citizen of the United States, anda resident of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and Improved Train-Doors Control, of which the following is a full, clear, and exact description.

My invention relates'to car-door openers, and has reference more particularly to means for opening, simultaneously all the car doors of a train from a station platform.

The object of the invention is to provide a simple, convenient and efficien ttrain-door control operable from the platform of a station, whereby all the doors of all the cars of a train can be simultaneously opened or closed by means of a contrivance provided on the platform of the station;

'With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure l is an elevation of a car equipped with means whereby the'doors can be operated from the platform of astation; Fig. '2 is a section through the platform of a station showing the means whereby the doors are operated; Fig. 3 is aperspective view of the shafts and brackets through the medium of which the operation of the car doors is obtained; and Fig. is a diagrammatic view of a train section at the platform' with the doors-controlling means on the platform in operative engagement with the means on each car of the train for operating its doors. Referring to the drawings, 4 represents a subway car in which a door 5 is operated through the medium of levers connected'to an air motor 6 located on the frame of the car (shown in dotted lines in Fig. 1). The air motor is controlled by a link 7 connected by means of a crank 8 to a rocking shaft 9, which at present is operable from the end doors of the car. The above-described parts are in use at present on subway cars and do not constitute part of my invention. 8

To operate the doors 5 of all the cars of a train simultaneously from the platform, I provide a rod 10 which extends parallelly to v Specification of Lette -rs Patent.

A. 'CONKLIN,

are, therefore, added to the mana e Nov. 2, 1915.

therocking shaft 9'a'nd to which it is connected by armsll. These parts 10 and 11 present equipment of the cars. g

The platform -12 of the station carries a shaft 13 which is mounted'in suitablebearings 14 so that its axis is parallel tothe axis of the rocking shaft 9 and, consequently, to

the 1-od .10. The said shaft 13 is of a length exceeding the maximum length of a train,

so that a] train containing the maximum number of cars is in operative relation with said shaft 13. 'Mounted rigidly on the shaft 13 are U-shapedbrackets 15 which 'exte'nd from the'platform toward the cars of the train, so that the rods 10 of the cars will easily engage between the branches of the U- shaped brackets 15. The distance between the ends of the branches is great enough to easily accommodatetherebetween the rod 10 and the ends of the arms 11, so that when said bracket 15 is in normal position there is ample play between the branches of'the U- V shaped bracket and the rod'10,'and no in terference can take place therebetween -while a moving train approaches or'leaves the platform12. One of the said brackets '15 has, preferably, an extension or lug 16 which is connected by a rod 17 to a hand he ver 18 mounted on the platform, and the movement of which is controlled by a sector 19 provided thereforon the platform. -It is self-evident that in place, of the lug 16a crank arm can be secured to the shaft 13, the result being thesame.

When a train stops at the platform 12,

the rod 10 of each car will find itself between the branches of a few of'the brackets 15 carried by the shaft13. By forcingthe lever 18 in the direction of the arrow, the

upper branches of the brackets 15 will be brought into engagement with the rods 10 therebetween, causing the shaft 9 to rock, and, consequently, operating the air motors 6, which will open the doors. By moving the lever 18 in the opposite direction, the lower branches of the brackets 15 will come into engagement with the rods 10 and cause i theshafts 9 to rock to their original posiout of the station.

From the above description it will be seen that all of the car doors of a train can be simultaneously opened and closed by means of the contrivance herein disclosed; and this is done by the means provided on the station which are adapted to operate the shafts 9 which control the air motors for the operation of the car doors.

It is self-evident that in lieu of the lever 18 a mechanism operable by compressed air or electricity can be substituted, and which most probably would be the case when the number of cars in a train is large.

\Vhile I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown ismerely illustrative and that such changes may be made as are within the scope of the appended claims.

I claim:

1. In combination with train car doors, means for operating the doors of each car and located on the car; and means located on the station platform for simultaneously actuating said means for operating the car doors of each car when the train is at rest in the station.

2. In Combination with train car doors, pneumatically operable means carried by each car for operating the doors thereof; and means located on the station platform for operating simultaneously said pneumatic means of each car of the train.

3. In combination with train car doors, pneumatically operable means controlling the doors of each car; a rocking shaft car ried by each car of the train and associated with the pneumatic operable means, and through the medium of which shaft the pneumatically operable means are controlled; and means carried by the station platform for operating simultaneously the said rocking shafts of all the ears of the train. i

4. In combination with train car dooi s, pneumatic operable means on each car for ope ating the doors'of the car; a shaft (in each car mounted to rock and associated with the pneumatic operable means thereon; and manually operable means located on the station platform and adapted to engage and rock the shafts of all the cars, whereby the doors of each car of the train are opened or closed substantially as described.

5. In combination with train car doors, pneumatic operable means provided on each car for operating the doors; a shaft on each car mounted to rock and associated with the pneumatic means; means in rigid connection witl said shaft extending therefrom; and manually operable means located on the platform and adapted to engage the means extending from the rocking shaft whereby said shafts are rocked and the doors of the cars operated substantially as described.

6. In combination with train car doors, pneumatic operable means associated with each car for operating its doors; a shaft on each car mounted to rock and associated with the pneumatic means of the car; a rod carried by each of said shafts; U-shaped brackets associated with the station platform and adapted to engage therebetween the rods carried by the shafts; and means for swinging said brackets whereby the shafts are rocked, causing the operation of the pneumatic means which control the car doors.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
